It supports a theoretical maximum throughput of 11 Mbps over short ranges using the 2.4GHz band. 802.11bĨ02.11b is one of the oldest Wi-Fi standards.
So if you find two products such as a Wi-Fi router and a Wi-Fi network card for a computer and both have the WiFi logo which includes the “ac” label then those products will be able to communicate with each other. The product has also been tested within Wi-Fi Alliance for those supported standards. The stamp consists of the “WiFi” brand in the middle, surrounded by a bunch of characters representing which Wi-Fi standards that the product can support. Any equipment that fulfils the requirements get the official stamp of the organisation which looks like this: All manufacturers within this organisation work together to test each other’s equipment against the equipment of other manufacturers so that they work together. To fix that problem for Wi-Fi networks almost all manufacturers agreed a long time ago to create an organisation called the “Wi-Fi Alliance”. This could prevent equipment from different manufacturers from working perfectly with each other. The standards for Wi-Fi communication are always named beginning with “802.11” and end with different characters such as “a”, “b”, “n” or “ac”.Įven though standards are developed by standards groups where experts from manufacturers and other organisations agree on how things should function a somewhat common problem with standards is that different equipment manufacturers might then not interpret the finalised standards in exactly the same way. There are a lot of standards for Wi-Fi networks and how they should operate.
